Abstract:

The physical adsorption of gases is the technique of first choice to study the characteristics of the pores originated in solid materials. The technique accurately determines the amount of gas adsorbed on a solid material, and it is considered as a direct measurement of textural properties in porous structures. In this Thesis, it is emphasized that these adsorption measurements are not as direct and infallible as usually described in the literature. The most common errors and limitations in the analysis of surface area and pore size distribution derived from adsorption/desorption isotherms of N2 at 77 K in mesoporous and microporous materials are identified and discussed in depth, with special emphasis on low-density mesoporous materials (e.g. aerogels) and in flexible microporous materials (e.g., MOFs and ZIFs).
